I did not read all the posts but seems like you want test your equipment quickly, pull the equipment and put it in a full sink and test each one the act of moving the pieces should be the final straw if something is close to being junk, also i think the build up in the piece of equipment will naturally try and equalize with the regular non salt water, making it trip out hard. Never use vinegar on pumps for an extended amount of time, if it has metal don't do it, better off chipping and scrubbing after a short soak like 1o-15 minutes. Just my experience had something doing similar put them in the sink and boom tripped out as soon as it touched the water, but was working for lengthy amounts of time in tank.
